# This WordPress cloud template is enhanced with comments to explain its
# parameters.
#
# Try cloning it and experimenting with its YAML code. If you're new to
# YAML, visit yaml.org for general information.
#
# The cloud template deploys a minimum of 3 virtual machines and runs scripts
# to install packages.

inputs:

# Choose a cloud endpoint. 'Title' is the visible

# Choose the operating system. Note that the Automation Assembler
# Infrastructure must also have an AWS, Azure, and vSphere Ubuntu image
# mapped. In this case, enum sets the option that you see, meaning there's
